Why would you choose one method over the other?

The usual answers are religious based.  Most women feel that natural insemination is "cheating" on their partner, and it is hard to deal with the mental anguish associated with not having been successful.  Thus a clinical artificial insemination might seem less "adulterous."

Typically, and artificial insemination requires some input from the medical community (freezing and thawing techniques, timing, etc.)  This obviously ads to the expense.

In the "natural" method, what is happening is pretty clear--but the mental anguish that an infertile father would have knowing that this method is used is often pretty tough to handle.

What I'd like to hear in this forum, is why someone would choose one way over the other.  Be those views religious, practical, mental, etc.

So what is your reason for choosing natural or artificial insemenation.

I think for many married couples and lesbians artificial insemination is the only way their partner would agree to using a donor. 

I think artifial is the best way because it's more of a business interaction and not likely for some hidden motives to be involved on the part of the donor.
